Endaweni yokusebenzela ye-Jinbin, iqoqo lamavalvu uvemvane ane-eccentric eqinile elivalwe ngokuqinile selizothunyelwa, anosayizi abasuka ku-DN65 kuya ku-DN400. Okuvalwe kanzimatriple eccentric butterfly valveiyi-valve yokuvala esebenza kahle kakhulu. Ngomklamo wayo oyingqayizivele wesakhiwo kanye nesimiso sokusebenza, ibambe isikhundla esibalulekile emikhakheni eminingi yezimboni. Isakhiwo saso "se-eccentricities ezintathu" sigqamisa umklamo oyinhloko: ii-valve ye-butterfly eqinilei-stem axis iyachezuka kusukela kukho kokubili isikhungo sovemvane kanye namaphakathi nomzimba we-valve, futhi ngesikhathi esifanayo, umugqa omaphakathi wendawo eyikhonikhali evalayo une-Engeli ethile eccentricity ngokuhlobene nomugqa omaphakathi wepayipi.

Lo mklamo wesakhiwo wephula umthetho wokunyakaza wamavalvu ovemvane endabuko. Lapho i-valve ivulwa, ipuleti levemvane nesihlalo sevalvu kuyanqanyulwa ngaso leso sikhathi. Phakathi nenqubo yokuvala, ipuleti uvemvane kancane kancane lisondela esihlalweni se-valve, futhi ekugcineni lifinyelela ukuvala ngokucindezela okuhlangene kwamapheya okunwebeka noma okuvala insimbi. Lesi sakhiwo sigwema ngokuphumelelayo ukungqubuzana phakathi kwepuleti le-butterfly kanye nesihlalo se-valve ngesikhathi sokuvula nokuvala inqubo, kwandisa kakhulu impilo yesevisi ye-pair yokufaka uphawu, futhi ngesikhathi esifanayo kunciphisa i-torque yokusebenza, okwenza ukuvulwa nokuvala kwe-valve kukhululeke futhi kube lula.

Uma kuqhathaniswa nezinye izinhlobo zama-valve, i-valve eqinile ye-Seal butterfly inezinzuzo eziphawulekayo. Okokuqala, inokusebenza okuhle kakhulu kokuvala. Isakhiwo sensimbi esiqinile singafinyelela ukuvuza okuyiziro futhi simelane nezingcindezi ezifinyelela ku-1.6MPa – 10MPa, sihlangabezana nezidingo zezimo ezihlukahlukene zokusebenza ezinomfutho ophezulu. Okwesibili, inokugqoka okuqinile nokumelana nokugqwala. Yenziwe nge-alloy eqinile ekhethekile noma izinto zensimbi engagqwali futhi isengasebenza ngokuzinza ezindaweni ezinokhahlo ezifana nezinga lokushisa eliphezulu, umfutho ophakeme kanye nokugqwala okuqinile. Okwesithathu, inokuphila kwesevisi ende. Ngenxa yokunciphisa ukugqokwa phakathi kwezingxenye, impilo yayo yesevisi ingafinyelela ngaphezu kweminyaka eyi-10 ngaphansi kwezimo ezijwayelekile zokusebenza, kwehlisa kakhulu izindleko zokulungisa. Okwesine, kulula ukuyisebenzisa futhi ingashayelwa ngezindlela ezihlukahlukene ezifana ne-manual, ugesi kanye ne-pneumatic, ukuhlangabezana nezidingo zokulawula okuzenzakalelayo ezimeni ezahlukene.

Ekusetshenzisweni okungokoqobo, i-valve uvemvane ene-eccentric evalwe kanzima kathathu isetshenziswa kakhulu ezimbonini eziningi. Emkhakheni we-petrochemicals, isetshenziselwa ukulawula ukuthuthwa kwemidiya efana ne-petroleum, igesi yemvelo kanye nezinto zokusetshenziswa zamakhemikhali; Embonini yamandla, ukuhamba kwemidiya efana ne-steam namanzi apholisayo kungalungiswa ukuze kuqinisekiswe ukusebenza okuzinzile kwempahla yokuphehla ugesi. Embonini ye-metallurgical, iyasebenza kumasistimu wamapayipi wemidiya efana ne-blast furnace gas, umoya-mpilo, ne-nitrogen. Emisebenzini yokuhlinzeka ngamanzi kanye ne-drainage, ngokuvamile isetshenziselwa ukusika amapayipi kanye nokulawula ukugeleza kwamanzi emadolobheni kanye nezinhlelo zokuhlanza indle.

Mayelana nemidiya esebenzayo, i-valve yevemvane eyi-triple eccentric yase-China inokuhambisana okuqinile. Ngokuphathelene nemithombo yegesi, ingasetshenziswa kugesi yemvelo, igesi yamalahle, umoya-mpilo, i-nitrogen, isitimu, njll. Ngokwemithombo ye-liquid, ingakwazi ukuphatha i-petroleum, izixazululo zamakhemikhali, indle, amanzi olwandle, njll. Ngaphezu kwalokho, kweminye imithombo ye-gas-solid noma i-liquid-solid exubile equkethe izinhlayiya nothuli, le valve ingakwazi futhi ukuphatha kahle ukuzivumelanisa nezimo, ukubonisa.
